Cops received a call about a brawl going down inside the gas station around 2:33 AM. We’re told an off-duty police officer from Atlanta happened to be at the same gas station and sprang into action — successfully breaking up the fight.

When on-duty cops arrived to the scene … Scrappy and the other man were arrested for disorderly conduct and hauled to a nearby police station. FYI — the other guy in the fight was Kenny Rogers … not “The Gambler” Kenny Rogers … just a random guy who also happens to share the same name as the country legend. We’re told Scrappy was very cooperative once in custody — and was released a short time later.

We spoke with Scrappy who insists Kenny Rogers was the aggressor — “He was calling my girlfriend names and then put his hands on me … so I had to lay them paws on him.”Scrappy’s lawyer Mawuli Mel Davis tells us there’s video that proves Scrappy was acting in self-defense.

Maybe next time Rogers will learn to mind his biznayee. Wait, did we just say that?
